At the Jan. 31 meeting of the Distributed Energy Resources Subcommittee, PJM and stakeholders reviewed different approaches to market rules for sites that host both wholesale DER and demand response resources.

Members also listened to a stakeholder proposal for market rules for combined wholesale DER and load response resources (with an energy market example). Comparisons were drawn between the PJM proposal, which is to separate these into distinct resources, and the integrated approach taken in the stakeholder proposal.

PJM also presented possible changes to gain visibility of non-wholesale DER resources (slides 9-10) within the PJM footprint. Non-wholesale DER is generation (including storage) that does not participate directly in the wholesale markets (either as front-of-meter generation or demand response) and is used to self-serve load.

Monitoring Analytics led a discussion on market power, the three pivotal supplier test and cost-based offers. The three pivotal supplier test measures the degree to which the supply from three suppliers is required in order to meet the demand in the relevant market, potentially giving them market power.

Stakeholders provided areas of interest at the Feb. 2 Summer-Only Demand Response Senior Task Force meeting and debated what design components should comprise any solution that might be proposed within the task force. The conversation centered less on the components than on why stakeholders are interested in examining certain solutions.

PJM will look at the input and see what themes emerge before the next task force meeting on Feb. 14.
